<p>In recent decades the literature on rescue systems has recorded a very<br />large number of contributions that have used, while declining according<br />to different perspectives, the Queue Theory to prepare procedures<br />and models to understand their behavior, measure and optimize performance<br />in terms of efficiency of the service rendered in the territory<br />by these particular systemic structures so important from a social point<br />of view.<br />These are very complex structures because of the predictable and<br />unpredictable factors of variability that intervene both in terms of the<br />number of requests and the time necessary to satisfy them.</p>Michele Fasolo

2019-01-032019-01-0315Studio comparativo tra lo stato dei luoghi prima e dopo l’incendio del Vesuvio tramite analisi satellitarehttp://ojs.mediageo.it/index.php/GEOmedia/article/view/1593
<p>At the half of July 2017, a big wildfire destroys a large area of Vesuvio and Mount Somma in the Vesuvio National Park. In this work, we have used Landsat8 multispectral set of images to study the area before and after the fire.</p><p>We have used tiles of 05-05-2017 and 24-07-2017. On the set of the images, we have applied the DOS for pass from TOA (Top Of the Atmosphere) to BOA (Bottom Of the Atmosphere). After this correction, we have applied<br />the Pansharpening with the aim of improving images resolution from 30m/px to 15m/px. Therefore we have estimate NDVI (Normalized Difference Vegetation Index), NBR (Normalized Burn Ratio) and temperature of<br />the ground before and after the fire.</p>Massimiliano MoracaAntonio Pepe

<p>«Nel campo della fotografia esisteva prima della guerra una sezione<br />fotografica dell’Esercito, ben nota soprattutto per le opere di Tardivo in telefotografia e telefotografia aerea. Queste trovarono immediata applicazione in guerra; e fosse dal cielo, dalla terra o dal mare, gli esploratori fotografi, utilizzando il buon apparato progettato e costruito dalla Sezione [Fotografica del Genio], hanno dato un contribuito reale alla conoscenza delle posizioni nemiche. La telefotografia è stata molto usata, soprattutto nelle regioni alpine, e, quando la censura lo ha consentito, i risultati sono stati in parte pubblicati, come per esempio i panorami della guerra preparati sotto la direzione del<br />Comando Supremo dell’Esercito».</p>Elizabeth Jane Shepherd

<p>The problems to be overcome to deal with emergency situations in case of natural disasters can be many and, especially in recent years, require specific skills in various areas. In particular, in-depth knowledge of all those platforms that can support decisions to be taken in risk situations is increasingly<br />necessary: the so-called DSS (Decision Support Tools). Let's see which are the limits of current emergency plans on a territorial scale, how they can be improved and the role of decision support tools.<br /><br /></p>Stefano MarsellaMarcello Marzoli

<p>The ex-President of the Italian Society of Photogrammetry and Topography (1995-1998) returns to a subject really dear to him: the reforms on the profession of Surveyor, the proliferation of the Bachelors Degrees for Surveyors and the shameful elimination of the Geodesic Commission of the Italian Republic, deemed "useless institution".</p>Attilio Selvini

<p>The support of digital cartography is now very widespread in the management of information and the National Fire Brigade, now for several years, studies the possible applications of this technology to emergency technical rescue activities.</p><p>These IT tools are very useful in management assessments during the alert, alarm and emergency phase, favouring the prediction and assessment of remote damage scenarios.</p><p>The systems allow the reading of data directly from digital cartography, from which "hidden" information can be deduced, in addition to those already reported in symbols in the initial screens. Moreover, the systems allow an easy comparison between the information on different maps, which can be read directly together on the same map.</p><p>The article illustrates the experience of the Frosinone VVF Command in the development of a cartographic platform, in which the different damage scenarios resulting from a hypothetical flood in the Municipality of Sora were simulated.<br /><br /></p>Fabio CuzzocreaStefano Lucidi

<p>Satellite navigation systems are more and more used in geomatics.<br />This penetration has not always taken into account the relative safety and security aspects and the consequent threats to humans. This work focuses on these aspects that are often overlooked in geomatics. After a brief introduction<br />on the evolution of satellite navigation systems and on future trends, the related safety and security risks are analyzed and possible countermeasures (Integrity, Awareness and Protection) are discussed.</p>Mauro Leonardi
